no response from usart - stm32f3 discovery

I have been trying to get the USART to work on the stm32f3 discovery for a while without any success. Currently, the TX pin (PA2) is at a constant 3.3V, the RX pin (PA3) is at a constant 0V. I am using an FTDI Basic breakout board to read the USART, and I am using the keil uvision 5 IDE.
